The Stereo Clone Theory is a stereo version of the famous pedal of the same name by Electro Harmonix, only in a smaller, tougher box. The Clone Theory produces warm Chorus sounds as well as classic pitch altering Vibrato tones. A super slow and subtle chorus can add dimension and richness to your rig, and when used in Stereo Mode, your guitar will sound huge! The Vibrato mode disables the dry signal to allow for warped record sounds or ray gun effects! For a truly lush, spacious guitar sound, check out the Stereo Clone Theory. Knob Controls include Chorus/Vibrato mix, Rate, and Depth.
